Struct ed25519_dalek::pkcs8::KeypairBytes

pub struct KeypairBytes {
    pub secret_key: [u8; 32],
    pub public_key: Option<PublicKeyBytes>,
}

Available on crate feature pkcs8 only.

Ed25519 keypair serialized as bytes.

This type is primarily useful for decoding/encoding PKCS#8 private key files (either DER or PEM) encoded using the following traits:

• DecodePrivateKey: decode DER or PEM encoded PKCS#8 private key.
• EncodePrivateKey: encode DER or PEM encoded PKCS#8 private key.

PKCS#8 private key files encoded with PEM begin with:

-----BEGIN PRIVATE KEY-----

Note that this type operates on raw bytes and performs no validation that keys represent valid Ed25519 field elements.

Fields

secret_key: [u8; 32]

Ed25519 secret key.

Little endian serialization of an element of the Curve25519 scalar field, prior to “clamping” (i.e. setting/clearing bits to ensure the scalar is actually a valid field element)

public_key: Option<PublicKeyBytes>

Ed25519 public key (if available).

Compressed Edwards-y encoded curve point.

Implementations

impl KeypairBytes

pub fn from_bytes(bytes: &[u8; 64]) -> KeypairBytes

Parse raw keypair from a 64-byte input.

pub fn to_bytes(&self) -> Option<[u8; 64]>

Serialize as a 64-byte keypair.

Returns

• Some(bytes) if the public_key is present.
• None if the public_key is absent (i.e. None).
